(Cl. 3615)The present invention relates to shoe construction, more particularly tothe construction of a shoe comprising a metal insole which is especiallyadapted for securing the upper portion of the shoe thereto by gluing orby screws.

Previously, shoes have been made comprising wooden insoles to which theupper portions were attached. These upper portions, however, becameeasily detached from the insole, and consequently the shoe did not lastlong. In addition, difficulties were experienced in rigidly connectingthe upper shoe portions to the wooden insoles.

To eliminate the disadvantages of shoes comprising wooden insoles, thepresent invention proposes a shoe comprising a metallic insole formedfrom a light alloy casting or stamping. The metallic insole has slotsalong its edges into which projections from the upper portions of theshoe are inserted and attached to the under side of the shoe by gluingor by other fastening elements.

There is a raised edge around the periphery of the sole to form a seatto retain a rubber or composition outsole therein. Transverse ribs arealso provided in order to secure the rubber outsoles againstlongitudinal movement. A metallic hollow heel is fastened to the heel ofthe metallic sole in a conventional manner.

It is therefore the principal object of this invention to provide alightweight shoe having great strength and durability and being moreattractive in appearance than previously known shoes.

It is a further object of this invention to provide a shoe constructionutilizing a lightweight metal alloy as an insole.

Other objects and advantages of this invention will become apparent uponreference to the accompanying description and to the following drawings,wherein:

Figure 1 is a top plan view of the metallic insole with the upper shoeportions being removed;

Figure 2 is a side elevational view of the shoe constructed inaccordance with the teachings of this invention;

Figure 3 is a bottom plan view of the metallic insole as illustrated inFigure 1 with the rubber outsole removed so as to show the details ofconstruction on the under surface thereof;

Figure 4 is a longitudinal sectional view of the metallic insole asshown in Figures 1 and 3 taken along the lines 4-4 of Figure 1;

Figure 5 is a plan view of the rubber outsole;

Figure 6 is a transverse sectional view of the improved shoe which showshow the projecting strips of the upper portion of the shoe are attachedto the underside of the insole; and

Figure 7 is a partial view of Fig. 6 showing more clearly how aprojecting strip of the upper shoe portion is disposed intermediate theinsole and the outsole.

Returning now to the drawings, wherein like reference symbols indicatethe same parts throughout the various views, there is shown in Figure 1a lightweight metallic insole 1 constructed in accordance with theteachings of this invention. The insole is formed from a light metallicalloy such as from aluminum or magnesium and is fabricated by casting orstamping. There are a plurality of longitudinally extending slots 2along each one of the longitudinal edges of the insole 1. There is araised edge 3 extending around the entire periphery of the metal sole 1,as shown in Figure l, to form a seat for a rubber or composition outsoleindicated at 4. The outsole 4 is secured to the under side of the insole1 by glue or by screws. There are a number of cross ribs 5 which can beseen in Figure 3 on the under surface of the insole 1 to preventlongitudinal displacement of the outsole 4. In addition, ribs 6 and 7are also formed on the under side of the insole 1 for further definingthe space to receive the rubber outsole 4. The rib 6 is particularlyintended for securing the rubber outsole 4 against movement.

The heel of the sole comprises a plurality of reinforced ribs 8 at thecenter of which is secured a stud 9 to which a heel 10 can be screwed ina conventional manner. The heel 10 is preferably hollow and formedentirely of metal in a known manner.

The upper portion of the shoe indicated at 11 in Figure 2 comprises anumber of projecting strips 12 which are inserted into the correspondingslots 2. The strips 12 are then folded under the insole 1 and aresecured thereto by gluing, screws or other fastening means such asrivets.

The finished shoe can be exposed to an oxidizing anodic treatment, andthe resulting oxide layers can be colored as desired in order to produceshoes of various colors.

Thus it can be seen that the present invention provides a lightweightshoe construction which has considerable strength, since the insole ofthe shoe is formed from a lightweight metal stamping or casting and theupper portions of the shoe are secured thereto.

It will be understood that this invention is susceptible to modificationin order to adapt it to different usages and conditions, and,accordingly, it is desired to comprehend such modifications within thisinvention as may fall Within the scope of the appended claims.

What is claimed is:

1. In a shoe having a detachable sole portion, a unitary light alloymetallic insole of cast material, a raised edge around the entireperiphery of said metallic insole so as to form a seat for an outsole,and a plurality of ribs normal to said raised edge on the under side ofsaid insole.

2. A shoe comprising a unitary light alloy metallic insole of castmaterial, there being a plurality of longitudinally extending slotsalong each of the longitudinal edges of the metallic insole, an uppershoe portion having a plurality of strips inserted into said slots andsecured to the under side of said insole, a raised edge around theentire periphery of the metallic insole so as to form a seat for anoutsole, and a plurality of ribs normal to said raised edge on the underside of said raised insole to prevent longitudinal displacement of anoutsole.

3. In a shoe having a detachable sole portion, a unitary light alloymetallic insole of cast material, and a raised edge around the entireperiphery of the metallic insole so as to form a seat for an outsole.
